Example Sentences

The fundamental interactions between lattice and spins underpin many physical effects that give rise to unusual -- and potentially very useful -- material properties: for example, high temperature superconductivity.

From Science Daily

In contrast, Anderson expounded the concept of emergence, which stated that as any system grew larger, new phenomena—such as antiferromagnetism and superconductivity—could emerge that could not be predicted from the fundamental interactions.

From Science Magazine

For instance, the fundamental interactions between elementary particles are mediated by particles such as photons1.

From Nature

In later work, she helped put a rigorous mathematical underpinning to techniques widely used by physicists in quantum field theory to describe fundamental interactions between particles and forces.

From New York Times

This is the question of why gravity is so much weaker than the other three fundamental interactions between particles, namely electromagnetism and the weak and strong nuclear forces.
